In mathematics, the Langlands classification is a description of the irreducible representations of a reductive Lie group G, suggested Robert Langlands (1973). There are two slightly different versions of the Langlands classification. some irreducible representations of a finite group Sφ. This leads to a space Key words and phrases.
